Title: Apparatus for aerating sewage
Inventor: NISHIDA SOUICHIROU
IPC: C02F3/12
Filed: 1982-06-16
Abstract: PURPOSE:To reduce the using amount of a neutralizer, by a method wherein a high concn. oxygen-containing gas is supplied in the vicinity of the bottom part of an aeration tank in oxyen aeration and air is supplied to the vicinity of the water surface therein to prevent the lowering in the pH of the mixed liquid in the tank. CONSTITUTION:Sewage is supplied into an aeration tank 1 by a conduit 1a and, when a recirculation pump is operated, the liquid of the upper part within the tank 1 is pumped up by the pumping-up pipe 2b of a recirculation pipe 2 to be discharged to the bottom part of the tank 1 through a flow-down pipe 2a. In this case, a high concn. oxygen-containing gas is supplied to the recirculation liquid from an oxygen generating source 6 through a supply pipe 3 or the way of the recirculation pipe 2. On the other hand, an air supply means 5 formed by providing air diffusion nozzles to a pipe is provided to the upper part of the aeration tank 1 and air is supplied into the liquid in an amount required in stripping carbon dioxide by aeration. By this method, aeration is carried out wall and the lowering in the pH of the mixed liquid is prevented.

Abstract: PURPOSE:To prevent defective operation of a change-over mechanism due to heat thereof and improve the injection property and combustion property of fuel by providing a check valve having high heat resisting property and pressure resisting property in the change-over mechanism for a pressurized air supply source. CONSTITUTION:While a fuel injector Z1 supplies pressurized air from an air tank 3 to a fuel injection valve 2 in the start of an engine having low discharge pressure of a compressor 1, it shuts off air from the tank 3 to supply pressurized air from the compressor 1 when the discharge pressure reaches at least a set value. A check valve 15 having high heat and pressure resisting properties is arranged at the very hot air path 21 side of this change-over mechanism so that a solenoid change-over valve 6 and a constant differential pressure valve 7 in an air path 22 connected from the air tank 3 to the downstream air side of the check valve 15 are not exposed directly to hot air from the compressor 1, the solenoid change-over valve 6 does not have any defective operations due to temperature rise and the change-over operation of an air supply source has no troubles.

Title: Controller for automatic transmission
Inventor: NAGAOKA MITSURU
IPC: F16H61/02
Filed: 1996-03-31
Abstract: PROBLEM TO BE SOLVED: To favorably execute subsequent feedback control by correcting operating pressure to a frictional element while feedback controlling the rotation of a turbine. SOLUTION: In this controller for an automatic transmission, a torque ratio is increased when a speed ratio is diminished, and the maximum value of the torque ratio, that is, the maximum torque ratio can be obtained when the speed ratio is 0. Therefore, in the case that a turbine rotational speed is detected at a small value by a turbine rotary sensor 305, the torque ratio is largely calculated so that oil pressure and line pressure are required to be at high values. Hereby, when the turbine rotational speed is small at the time of a low vehicle speed, especially, when an input torque is large at the time of starting, high operating pressure is supplied to a frictional element so as to prevent slip. The operating pressure to the frictional element is thusly corrected, therefore subsequent feedback control is favorably executed from the first.

Abstract: PURPOSE:To exactly detect signals regardless of a difference in the reflectivity of the fundus oculi, variable power, etc., by providing this system with an arithmetic means for determining a differential signal between the signal obtd. from a photoelectric converter at the time of projecting an index and the signal obtd. at the time of non-projecting and outputting a focusing signal, and a driving means capable of varying the accumulation time of this photoelectric converter. CONSTITUTION:The light from a light source 16 forms an image after passing a slit. This light is again imaged near a holed mirror 9 and is further imaged near the pupil of the eye 12 to be inspected by an objective lens 11, by which the fundus oculi is illuminated. The slit image from the fundus oculi is imaged near an array sensor 23 by a reimaging lens 21. The signal outputted from this array sensor 23 is amplified by a programmable amplifier of a variable gain and the gain of the amplifier by a field angle is controlled by a microcomputer. Only the signal component is obtd. by obtaining the difference between the output of the array sensor 23 when the light source 16 for projecting the index is lighted and the output when the light source is put out. The focusing information is thus obtd.

Title: Facsimile equipment
Inventor: KAKEYA MASAO
IPC: H04M11/06
Filed: 1986-05-06
Abstract: PURPOSE:To shorten communication time in terms of standard facsimile communications by attaining a call over the phone even during a start protocol executed after and before the exchange of facsimile picture information and simultaneously advancing the start protocol for facsimile communications during a call. CONSTITUTION:While a facsimile control signal is being exchanged, relays RC1 and RC2 are connected to the side of a contact point (b). After a band-pass filter BPF 3 takes out only the prescribed band(about 1750Hz) of the facsimile control signal modulated into 300 baud in a MODEM 4, said band is transmitted to a mixing part 3. If a transmission side places a call over the phone during sequence start and end protocols, a band removal filter BEF 1 removes the signal about at 1750Hz among sound signals, and the mixing part 3 synthesizes it with the facsimile control signal. The synthesized signal is transmitted to a telephone line N through a relay 6, a hybrid circuit 2 and the relay RC1. Thus a sound and the facsimile control signal can simultaneously be transmitted, and the total communication time is shortened.

Abstract: PURPOSE:To regulate the distribution of charging materials and to improve productivity by providing levelers right under armor plates provided in order to disperse the charging materials falling into a furnace and sliding the same in the furnace center direction from a furnace wall part. CONSTITUTION:Charging materials falling into a furnace top through a large charging bell 1 of a blast furnace collide against armor plates 9 which are disposed in plurality annularly on the inside circumference of the furnace wall and are freely movable in the direction radial to the furnace center, by which they are repulsed and dispersed. The charging materials in the furnace center part that exceed the dispersion limits thereof are leveled off by levelers 29 provided in the positions below the plates 9, whereby the accumulation state of the ore and coke in the direction concentrical with the furnace circumference is made uniform. While the charging materials in the furnace descend in the furnace on progression of iron making reaction, the levelers 29 operate to push the charging materials into the central part, thereby providing adequate distributions.
